文摘目的探究宏基因组二代测序(metagenomic second-generation sequencing,mNGS)技术在早期检测腹膜透析相关腹膜炎(peritoneal dialysis-associated peritonitis,PDAP)患者细菌感染的病原学价值,了解不同细菌感染类型中细胞因子分布差异,构建相关风险预测模型。方法收集2020年4月─2023年4月就诊于安徽医科大学第一附属医院,符合国际腹膜透透协会(international society for peritoneal dialysis,ISPD)诊断标准的腹膜透析(peritoneal dialysis,PD)患者的临床资料,同时将其入院4小时内PD流出液送检mNGS检查及普通培养,并测定上清液中细胞因子水平,比较mNGS检测与实验室微生物培养病原学诊断结果,综合临床意义分为革兰氏阳性菌(G+菌)组、革兰氏阴性菌(G-菌)组和培养阴性(G0)组,比较2组细胞因子水平差异,确认危险因素并构建风险预测模型,同时进行效能检测。结果共50例PD相关腹膜炎患者纳入本研究,mNGS检测中41例患者检出病原体,检测阳性率高于微生物培养(χ^(2)=0.059,P=0.440),mNGS检测时间低于微生物培养(t=5.180,P<0.001)。多因素Logistics回归分析提示PD液中高白细胞介素(IL)10(OR=1.010,95%CI:1.000~1.020,P=0.024)、低IL-6(OR=0.620,95%CI:0.360~0.890,P=0.038)及高血清降钙素原(OR=1.200,95%CI:1.050~1.530,P=0.016)、低C反应蛋白水平(OR=1.014,95%CI:1.010~1.050,P=0.035)为PDAP预测G-菌感染的独立危险因素。ROC曲线及列线图结果显示上述炎症因子联合较单一因子对预测G-菌感染价值更大。结论mNGS在早期快速检测PDAP病原体方面显示了极大的诊断潜力,PD流出液中细胞因子IL-6、IL-10及血清降钙素原、C反应蛋白水平的整合提高了mNGS结果解释的精确度,依据细胞因子构建的风险预测模型可以较好区分不同种类细菌相关PDAP腹膜炎的患者。
